Syrian government army re-established control over four oil fields in the provinces of Raqqa and Deir ez-Zor, Syrian state-run agency reported.

The oil fields of Wahhab, al-Fahed, Dubeisan and al-Kabeer and the wells of al-Qaseer, Abu al-Qetat and Abu Kattash were restored during the military operations, the agency quotes a source.

A military source told SANA on Saturday that heavy losses were inflicted upon ISIS terrorists during the military operations.
